Physics

An object with total mass m_total = 14.6 kg is sittingat rest when it explodes into three pieces. One piece with massm₁ = 4.7 kg moves up and to the left at an angle ofÎ¸₁ = 20Â° above the â€“x axis with a speed of v₁= 26.8 m/s. A second piece with mass m₂ = 5.1 kg movesdown and to the right an angle of Î¸₂ = 25Â° to the rightof the -y axis at a speed of v₂ = 23.5 m/s.
What is the x-component of the velocity of the third piece?
What is the y-component of the velocity of the third piece?
What is the magnitude of the velocity of the center of mass ofthe pieces after the collision?
Calculate the increase in kinetic energy of the pieces duringthe explosion.
